Can vvvv do what I need?

I coded a c++ application that takes a 3000 by 300 BMP image, averages all the RGB values for each of the 3000 columns. 0 to 255. This is saved to an 8 bit wav file. This is an audio version of the image exactly.

Like Variable Density film soundtrack. 0.5 second sample to loop as audio.

If I use vvvv to read an image file when triggered, can I do this conversion? And send output to audio device live.

Vvvv looks great for live visuals, I don’t expect a problem with that stage.

That should be doable. To get you started, look for “HowTo Patch a Multi-Channel Audio Generator” in the HelpBrowser.
